Lena displayed the historical photographs she located illustrating women's fashions in the 1880s , and we noted that as the Keller family was rich these fashions would have been worn by Helen Keller's mother if she were attending a formal event. I inquired as to the purpose of a key to which Lena responded , and I then explained the significance to the play of keys and locked doors as it is Helen who is locked within herself, and Annie Sullivan who must "unlock" her. We then began to read the play aloud with Lena and I taking the parts of the various characters. Lena read her lines very well and with enthusiasm !
